Generator speed and type of generator. In the case of a condensing turbine, the supplier will quote for the complete package for steam condensation and system for recycling of the condensate. 9. Load on the cooling tower. 2 Technical and Economic Considerations Some of the important considerations for cogeneration system are as follows: 1. Capital cost of steam turbo generator set consisting of (a) Turbine (b) Gearbox (c) Instrumentation (d) Other accessories for lubrication, bearing cooling, etc.
However, this route was found to present practical difficulties since the 40–42% oleums can solidify even at ambient temperatures at many locations. In practice, the strength is therefore brought down from 100% (which is pure SO3) to a level of 65% by adding 25–30% oleum in the required amount. This operation is carried out as follows. Batch operation: A known amount of liquid SO3 is taken in a tank equipped with outside cooling jacket and a circulation pump. A stream of 25–30% oleum is slowly added in a controlled manner while the circulation pump is running.
The entire system is under pressure. The limitation of this process is that the HCl and SO3 gases are required to be fed at high temperature of about 90–100 °C. Another limitation of this process is that this cannot take gases directly from electrolytic cells producing HCl gas due to the danger of explosion (since a mixture of hydrogen and oxygen is formed after HCl is absorbed). In view of the large volume required, the basic drawback in this process is that the equipment can produce only small tonnage— around 20–30 TPD.
